In the past I remember reading some articles about anchor ponits.I remember one article stated that shooters who wear glasses and use their nose as one of their anchor points are better off to have the string along side their nose rather that using the tip of their nose.
I wear glasses and can shoot both ways ie:tip of nose or along side the nose both with the same accuracy.
Seems to me that if you have the string along side the nose then your drawlength is probably a shade too long.
What is the theory of eyeglass wearers and why should they use the side of nose rather than the tip?
